RECORD-RESURFACING MACHINE.

Application. filed July 30,

This invention relates to record-resurfacing machines, and moreparticularly to machines for shaving record-blanks, intended for usewith dictation machines.

An object of the present invention is to provide improved means forrigidly mounting the record-resurfacing tool so as to prevent vibrationthereof, and thus permit a smoother surface to be obtained on theresurfaced record blank.

Another object of this invention is to provide improved means forquickly and easily locating and locking the record resurfacing tool withrespect of the record in proper 1 positionfor taking'a'first orpreparatory cut of predetermined depth.

Another object of the present invention is to provide improved means forautomatically advancing the resurfacing tool for one or more finishingcuts of predetermined depth to be taken after the first or preparatoryout has been made.

A still further object of the present invention is to provide means forcausing the return of both the record-engaging tool and the advancingmechanism therefor to normal position by a single manual operation.

Other features and advantages will hereinafter appear.

In the accompanying drawings which show one form of the invention, thatat present preferred- Figure 1 is a rear elevation of arecordresurfacing machine made in accordance with the present invention,the resurfacing tool (a shaving knife in this case) being in theposition it'usually occupies after a record is shaved and before theknife-bar carriage is moved toward the left as viewed, to startingposition.

being returned to position to start shaving a record.

Fig. 5 is a top plan View of the parts in the positions shown in Fig. 1,and showing the gage-bar and knife-bar mounting in dotted lines todisclose the operative relation between the gage-bar and knife-bar andthe record blank when the knife-bar has been set to take a first orpreparatory cut.

The shaving machine shown in the accompanying drawings is particularlyadapted for shaving or otherwise resurfacing phonograph record blanks,particularly those adapted to be used with dictation machines. Itcomprises a frame 10 provided with a left-hand standard 11 and righthandstandard 12. Supported between the standards 11 and 12 is a guide rod 13adapted to receive a carriage 1(1 whose forward end is provided with ashoe 15 adapted to ride on a rail 16 forming part of the frame 10. Theknife-bar carriage 14 extends forwardly and upwardly from the guide-rod13 to a point above the rail 16 where it is provided with a weight 17shaped to be conveniently grasped and to act as a hand-piece by means ofwhich the carriage is moved.

A mandrel 18 adapted to receive a recordblank 19 is supported on theframe to be traversed by the carriage 14, which is caused to travel onthe guide rod 13 and rail 16 relative to the record-blank 19 by a feedscrew 20 engaged by a feed-nut 21 mounted on the carriage 14:. Thefeed-screw 20 is caused to rotate coordinately with the mandrel 18 by aninterconnecting belt 22, and these rotatable members are usuallyactuated by an electric motor (not shown) mounted below the frame 10.

Phonograph record blanks are customarily cut or shaved to resurface themfor use when it is desired to obliterate an old rec- 0rd before making anew record on the surface of the blank. This operation may also beaccomplished by means of burnishing tools and other arrangements, and sofar as some of the salient features of the present invention areconcerned, it is immaterial whether the record-engaging tool used be aknife, a burnisher. or other device. However, since the method ofcutting is the one most frequently used and most preferable at present,means for that purpose is illustrated herein.

Accordingly, the machine shown in the accompanying drawings comprises aknifebar 23 adapted to carry at its forward end a knife 24 usuallyformed of sapphire or other hard stone, This knife-bar 23 is mounted onthe carriage 14: and is adapted to be moved so as to bring the knife 24into contact with the record-surface, so that simultaneous rotation ofthe record and travel of the knife with the knife-bar carriage 16 whilethe knife is in engagement with the record causes the top surface of therecord to be removed. The knife is preferably pr0- vided with chip'chute25 into which the shavings from the record pass and through which theyfall downwardly through a trough 26 on the frame 10 to a suitablecontainer provided for the purpose of receiving the chips.

The above described structure and mechanism is common torecord-resurfacing machines heretofore manufactured and used and form apartof the present invention only in so far as they are opcrativelyrelated to or combined with other mechanisms hereinafter described.

In order that the knife 24 may be quickly and easily set to properoperating position for taking the first or preliminary cut whenresurfacing a record-blank, the present invention provides improvedmeans whereby a direct manual operation, requiring no special attentionon the part of the operator, causes the knife-bar to be so set that theknife will extend into the record-surface only a predetermined and setamount, whereby the layer of record material removed will beof-predetermincd thickness,

This improved means, according to the present invention, comprises agage-bar 27 mounted in a housing 28 for the knife-bar and adapted toslide parallel therewith. The knife-bar 23 and gage-bar 27 are tiedtogether by a yoke or tie-bar 29 for movement en bloc in the housing 28toward and from the record-surface, so that, when they are movedforwardly toward the recordblank, the front face 30 of the gage willengage the record-surface and limit the extent of forward movement ofthe knife 24 beyond the record-surface. The knife-bar 23 and thegage-bar 27 and yoke are usually so interconnected and formed that theworking surface of the knife 24 usually extends beyond the workingsurface 30 of the gage-bar 27 by an amount equal to substantiallyfifteen thousandths of an inch. This, with an additional advance of livethousandths of an inch effected by means hereinafter described,represents the depth of a first or preliminary out.

It is sometimes desirable. however, to change the depth of cutdetermined by the g i 27, and this is accomplished according to thepresent invention by providing on the gage 27 a screw-threaded portion31 adjustable in a threaded section 32 of the lie-bar 2.) connected tothe knife-bar 23. These 1 arts are locked in the adjusted position by athreaded disc 33 which preferably has a cupped section 34-. which actsas a linger piece by means of which the gage-bar and the knife-bar aremoved toward the record 19.

In adjusting the go r'lJlil' 2 relative to the knife 2i, the disc .5 isfirst turned to release the screw portion ill and the latter is thenturned in the yoke, either to the right or left, until the desiredsetting is obtained, whereupon the disc 3:?- is turned to lock thegage-bar 27 against movement in the yoke 29. By this means, a person ofordinary mechanical skill can vary iln relation between the gage-bar andthe knife-bar so that the depth of cut may be changed to meet prevailingconditions.

The gage-bar, having been set relative to the knife to suit averageconditions, these parts are moved from normal inopcrat ive position to aposition for taking the first or roughing cut on a record-blank 12) bythe operator pressing his finger against the linger-piece 34- carricd bythe gagc bar until the flat end 30 of the gage-bar comes in coutact withthe recordsurface. at which time the edge of the knife will be locatedforwardly of the record a predetermined amount.

In making the shaving machine, the gagebar 27 may, of course, be locatedat cithcr side of the knife-bar 23. depending upon what point in theoperation of the machine it is desired to set the knife-bar 2 it isconsidered preferable, at PltFKlll'. to place the gage-bar 27 behind theknife-bu r Qtlfconsidering the direction of travel of the carriage whilethe knife is cutting, so tl at the gage-bar end 30 will always be above5lll l spaced from the record-s1u'face just shaved by the knife 24:.Moreover, when so placed. the gage-bar may be arranged to Contact withthe record, when setting the knife. while the knife is located beyondthe end of the record at the finish position of cutting travel, as seenin Fig. Hence the knife bar and gage may be moved into positio bv handas above described. without necessitating the pressing or forcing of theknife .4: into the record-surface, After this setting. the carriage ispivotally moved on the guiderod 13, then slid to starting position forcutting travel at the left side of the machine shown in Fig. 1, so thegage-bar end will trail. the knife 24: and be spaced from the shavedrecord-surface a distance substantially equivalent the depth of cuttaken as the cutter travels over the recordsurface toward the finishpositions.

The present invention also provides im proved means for locking theknife-bar 23 ill) in any manually adjusted position so that it will befirmly held in that position while shaving a record. This means, in theform shown in the accompanying drawings, comprises a shaft mounted torotate in the housing 28 adapted to extend transversely of the knife-bar23. The shaft 35 is provided with a cam section 36 adapted to engage aflat surface 37 on the bottom of the knifebar 23 so that, when the shaft35 is rocked by a spring 38 (Fig. 1), the cam section 36 will be broughtinto engagement with the flat surface 37 on the knife-bar to firmly lockthe knife-bar in place. The cam section 36 is so arranged that shouldthe knifebar 23 tend to move backwardly, it would cause the shaft 35 tobe rocked, thereby causing the cam 36 to more tightly and firmly engagethe knife-bar andprevent its further movement.

In order to advance the knife 24 step-bystep to take finishing cuts, ithas previously been proposed to slide the knife-bar and carrier thereforon the carriage to and from the record. It has also been proposed toallow falling movements of the carriage itself stepby-step to accomplishthis purpose.

According to the present invention, however, the step-by-stepadvancement of the knife 24 is accomplished by pivotally moving theknife-bar on the carriage, as distinguished from pivotally moving theknifebar with the carriage. Accordingly, the knife-bar carrier 28 of thepresent invention is pivotally mounted on a rod 39 carried in a pair ofears 40 and 41 formed integral with the carriage 14 and between whichears the end 42 of the cutter carrier 28 snugly fits. The shaft 39 isarranged parallel to the axis of the mandrel 18 so that when the cuttercarrier 28 is rocked on the shaft, the knife 24 will be moved toward orfrom the record, according to whether the knife-carrier 28 is given aclockwise or counter-clockwise movement, as seen in Fig. 3.

Normally, the knife-bar housing 28 is urged rearwardly, that is to say,away from the mandrel 18, by means of a spring 43 which is located inthe carriage 14 and which forces a plunger 44 upwardly against aforwardly extending arm 45 on the cutter-carrier 28. It is against thetension of the spring 43 that the cutter-carrier 28 is ad vancedstep-by-step to move the knife 24 closer to the record 19 for successivefinishing cuts. v

This step-by-step movement of the cuttercarrier 28 is controlled by acam disc 46 mounted on a stud 47 on the carriage 14, cooperating with aroller 48 mounted on a stud 49 carried by the arm 50 of the cuttercarrier 28. The spring 43 normally urges the knifebar housing 28rearwardly so that the roller 48 contacts with the surface of thecamdisc 46.

The cam disc 46 is provided with a series of ratchet teeth 51 adapted tobe engaged by a feed pawl 52 pivotally carried byv a pawlarm 53pivotally mounted on a stud 54 carried by the carriage 14. The ratchetteeth 51 are also engaged by a back-check pawl 55 pivotally mounted onthe stud 54 and normally urged by the weight of its arm 56 intoengagement with the ratchet teeth to prevent backward movement of thecam disc 46 against the tension of a spring 57 located in an undercutportion in the stud 58, see Fig. 4.

In order that the cam disc 46, and hence the knife 24, may be movedstep-by-step to accommodate for successive finishing cuts as an incidentto the movement of the carriage to position to start shaving a. record,the arm 53 of the feed pawl 52 isarranged to overlie a projection 59 onthe base plate 10 when the carriage is, as is shown in Fig. 1, in theposition at the end of a shaving operation. The parts are so arrangedthat when the carriage 14 is raised by means of the hand-piece 17 fromthe positions shown in Figs. 1 and 3 to that shown in Figs. 2 and 4, thelower portion of the pawl arm 53 engages the projection 59 on the frameand causes the pawl 53 to engage a ratchet tooth on the cam disc 46 andmove the latter an amount equal to the distance between two teeth, thepawl 52 at this time moving clockwise, as seen in Figs. 1 and 2, againstthe tension of its spring 60. While the cam disc 46 is being so moved,one of the ratchet teeth thereon passes the backcheck pawl 55 and thelatter then prevents the cam disc 46 from rotating backwardly until thedesired time.

This upward swinging movement of the carriage 14 is necessary to permitthe movement of the carriage to starting position, for by it thefeed-nut 21 is removed from the feed-screw shaft 22, as shown in Fig. 4,and the knife 24 and gage 27 are moved away from the record. With thecarriage so raised, it is moved longitudinally of the machine toward theother end of the record and, upon reaching that end, it is allowed todescend to cause the knife 24 to engage the record 19 and shave thesame.

During the movement of the carriage to starting position, the feed-pawlarm 53 slides off the projection 59 and is returned to its normalposition by a spring 61 wrapped around the stud 54 and having one endanchored in the pawl arm 53 while the other end is anchored in thecarriage 14.

If the first finishing cut is not su'liicient to provide a satisfactoryrecording surface on the record, additional finishing cuts may beobtained by again raising the carriage 14 and moving it to startingposition. Thus, without making any manual readjustments of the knife,the automatic advancing means, comprising the feed-pawl 52 and cam disk46 above referred to, will advance the knife by moving the knife-carrier28 arcuately toward the record during the raising of the carriage.

After the record has been satisfactorily shaved, it is desired to returnthe knife 24 and knife-bar carrier 28 with the step-bystep advancingmeans, comprising the cam disc 16, to normal position so that the knifemay be manually set to take a first or preparatory cut from a newrecord. To do this, the shaft 35, which has the cam surface 36 whichlocks the knife-bar 23 in the knifebar housing 28 against movement, isprovided with a lever 62 secured thereto and adapted to be manuallyoperated to rotate the shaft against the tension of the spring 38 tothus release the knife-bar 23. When so released, the knife-bar 23 isrestored to inoperative position by means of a spring 63 located in thehousing 28 between the housing and a collar 64 on the gage-bar 27 At thesame time, the knife-advancing cam disc 46 is released so as to permitits return by the spring 57 (see Fig. 4) by causing the back-check pawlto be disengaged from the ratchet teeth 51.

This is accomplished without requiring attention 011 the part of theoperator by providing a connection between the weight arm 56 of thebaclncheck pawl and an arm on the knife-bar lock lever 62, comprising alug 66 on the weight lever 56 of the back-check pawl adapted to extendinto an aperture 67 on the knife-release lever constituting thisconnection. Hence, when the knife-release lever 62 rotates with theshaft 35, the arm 65 thereon will raise the arm 56 of the back checkpawl lever 55 and remove the pawl from engagement with the ratchetteeth. By this operation, the cam disc 46 is permitted to be returned tonormal or initial position by the spring 57, because the feed pawl 52 isnormally out of engagement with the ratchet teeth 51. When the cam disc46 is returned to normal or initial position, it allows theknife-housing 28 to be swung to its normal or initial position by meansof the spring 43 provided for the purpose. The extremes of movement ofthe cam disc 46 is limited in both directions by a stop pin 68 engagingshoulders 69 on the cam disc.

The preparatory pivotal upward movement of the carriage 14, when movingthe carriage to position to start shaving, is limited according to thisinvention by an arm 70 mounted on the carriage engaging a rail 71provided on the base 10. The movement permitted by the arm 70 and rail71 is, of course, more than sufficient to move the knife-bar out ofengagement with the record and the feed-nut 21 out of engagement withthe feedscrew 20, but it is just sufficient to move the knife-advancingmeans the proper or requisite amount.

In order to insure that the carriage is raised sufficiently high to movethe knife-advancing means the proper amount, the present inventionprovides a pair of escapement lugs 72 and 73, the lug 72 being mountedon the carriage 14 and the lug 73 being mounted on the frame 10. Theselugs are normally arranged to be in the relative positions shown inFigs. 1 and 3 when the carriage is at the end of a shaving operation. Inthis position, the lug 72 is beyond the lug 73 and hence the carriagemay be swung upwardly without interference with the lug 7?). Should thecarriage be swung up partially. however, and not far enough to operatethe knife-advancing means, the lug 72 will be in position to be engagedby the lug 73 should an attempt be made to move the carriagelongitudinally. However, if the carriage is moved sul'iiciently, the lug7 2 is carried forwardly beyond the lug 73 as shown in Fig. 4, and inthis position longitudinal movement of the carriage is permitted.

It will be understood that the relative setting of the knife-bar 23 andthe gage-bar 27 is such that the amount of the lirst cut will be the sumof the amount by which the knife-bar protrudes beyond the ga e-bar andthe amount of advancement given to the knife by the means for advancingthe knife for a secondary cut, for the automatic knifeadvancing meansoperates when the carriage 14 is first raised after setting the knife byhand as well as during subsequent raising movements of the carriage aswhen taking successive finishing cuts.
